Specific implementation mode
The present invention is more specifically described in detail with reference to specific embodiment.
The present embodiment carries out Welding experiment to C1100 fine copper plate and Al5652 aluminium alloys, and welded specimen dimensions is：
70mm × 25mm × 0.8mm, without any surface treatment before sample welding.Sample is placed on chopping block and is welded, welding
Connector is joint form, lap of splice 25mm, and copper coin is placed on aluminium sample；Limited block is installed on chopping block, prevents from welding
Sample ensures that solder joint is located at overlapping regions center due to the larger offset of vibrations generation of tool heads in journey.
By obtaining electric current, the voltage signal of energy converter, judge whether welding point generates edge crack, key step is such as
Under：
(1) ultrasonic power of welding process is obtained in real time
The system structure of the electric current and voltage signal of energy converter is acquired in welding process, as shown in Figure 2.Select Current Mutual Inductance
Device measures ultrasonic electric current, and electric resistance partial pressure measures ultrasonic voltage, the signal that each sensor obtains after signal conditioning circuit is handled,
It is converted into the voltage signal of 0~10V, then uses data collecting card NI-6133 to acquire corresponding signal, Acquisition Circuit is as schemed
Shown in 3.Electric current, the amplitude envelope line of voltage signal and its corresponding phase difference are found out, and then calculates the ultrasound of welding process
Power P (t).
(2) relationship and its reason that power curve variation is generated with edge crack are determined
When amplitude is set as 80%, when weld interval is 1.1s, there is the isomerizing zone of part in interface, but does not split
Line, as shown in Fig. 4 (a)；When weld interval is 1.2s, crackle generates, and the as shown in Fig. 4 (b) is 90% and 100% in amplitude
When, it is observed that similar phenomenon.When amplitude is 90%, 0.7s does not have found that crackle, 0.8s crackles generate；Amplitude is 100%
When, 0.3s is not cracked, and 0.4s crackles occur.When amplitude is 80%, when weld interval is 1.1s, power curve is not shown
Write the phenomenon that declining；With the generation of edge crack, when weld interval is 1.2s, power curve is in 1.1s~1.2s time sections
Appearance is remarkably decreased amplitudes and was set as 90% weld interval when being 0.7s, the phenomenon that power curve is not remarkably decreased；When welding
Between when being 0.8s, edge crack generates, while power curve is remarkably decreased in 0.7s~0.8s time sections.Amplitude is set as
100%, when weld interval is 0.3s, the phenomenon that power curve is not remarkably decreased；When weld interval is 0.4s, it can observe
To edge crack, and power curve is remarkably decreased in 0.3s~0.4s, as shown in Figure 5.By ultrasonic bonding test with
And below known to theory deduction, ultrasonic power curve occurs being remarkably decreased with the generation of welding region edge crack
Its concrete reason is analyzed as follows
Ultrasonic power and the relationship of soldering tip shearing force are as follows:
P=Fs*vavg (1)
Wherein P is the mean power in a vibration period；FsFor soldering tip shearing force；vavgFor soldering tip average movement velocity.
It measures and understands through laser displacement sensor, the moving displacement of soldering tip can be expressed as
ξ (t)=ξ0Sin (ω t), f=| ω |/2 π (f=20kHz) (2)
Wherein ξ0For amplitude；ω is angular speed；F is ultrasonic vibration frequency.
Displacement derivation to soldering tip, certain a moment soldering tip movement speed are represented by
It differentiates again to soldering tip movement speed, then the translational acceleration of certain a moment soldering tip is
In signal period, the average movement speed of soldering tip is
Wherein T is the vibration period.
Formula (5) is substituted into formula (1), can be obtained
P=Fs*4*ξ0*f (6)
It can be obtained according to Newton's second law by Fig. 6
Wherein m is welding head quality, FIFor the frictional resistance by bit copper plate to soldering tip, F is by bit copper plate to the transverse direction of soldering tip
Deformation drag.
By formula (7), soldering tip shearing force is represented by
From formula (6), ultrasonic power is dependent only on soldering tip shearing force, Oscillation Amplitude and vibration frequency vibration frequencies
Rate is the generation of 20kHz. crackles, causes internal stress to redistribute, FLIs strongly reduced from formula (8), in identical amplitude
Under the conditions of, FLIt strongly reduces, leads to soldering tip shearing force FSThe feedback control system for strongly reducing supersonic welders is changed by adjusting
The output power of energy device ensures soldering tip and makees high frequency periodic to set amplitude and frequency and move since the generation of crackle causes to weld
Shearing force is substantially reduced, so required ultrasonic power is substantially reduced, the real-time adjusting through reponse system, under power curve is notable
Drop.

Time is respectively 0.7s and 0.8s；Amplitude is 80%, and weld interval is respectively the corresponding ultrasonic power dispersion numbers of 1.1s and 1.2s
Strong point P (t) imports the workspace in matlab, and the original power curve of acquisition is as shown in Figure 5.Pass through function smooth (P
(t), 9), ultrasonic power curve is smoothed, obtains smooth power curve Q (t), as shown in Figure 7.
(4) calculating of power curve change rate
By treated, the corresponding discrete data point Q (t) of power curve is imported in a manner of vector in matlab
Workspace, while by its corresponding weld interval tnThe workspace in matlab is imported in a manner of vector,
Command Window input K=gradient (Q (t)) ./gradient (tn), you can it is corresponding under the conditions of acquisition various amplitude
The change rate curve of power after smoothing processing, as shown in Figure 8.
(5) determination of threshold value
In the case where amplitude is 100% 90% and 80%, 0.3s repeatedly carried out to copper coin and aluminium sheet respectively, 0.7s and
The welding of 1.2s, will suitably extend 0.1s weld intervals, and welding point starts to crack.Extract the ultrasonic work(under each welding condition
Rate curve is smoothed it and calculates the corresponding change rate of smooth power curve each point successively.As shown in Figure 8,
Under conditions of amplitude is 100%, 90% and 80%, flawless generates corresponding power variation rate minimum value KminRespectively-
2600, -1800, -1000. when having crackle generation, corresponding power variation rate minimum value Kmin2Respectively -13333, -8900, -
In 3500. examples, the corresponding change rate of knick point power curve is that -3500. corresponding threshold value D are -3500, and the threshold value is big
The corresponding minimum value of power variation rate when cracking can effectively reject the welding point of crackle generation.
(6) whether judgement sample cracks
It according to the relationship between predetermined edge crack and power curve, can obtain, when power variation rate K is more than threshold value
When D, then welding region flawless phenomenon during ultrasonic bonding can be determined；When change rate K be less than or equal to threshold value D,
Power curve is remarkably decreased, then may determine that edge crack centainly occurs in welding region.
The method of the present invention finds that edge is split by the experiment of a large amount of ultrasonic wave dissimilar metal welding and theoretical validation first
The generation of line can lead to being remarkably decreased for power curve, then determine that a threshold value D, threshold value reflection power curve reach certain
Decline degree when, edge crack has generated.Specific embodiment is：Electric current, the voltage signal of extraction of transducer, Jin Erji
Calculate and obtain the ultrasonic power curve P (t) of welding process；It is smoothed, it is each then to find out corresponding smoothed curve
The change rate of discrete point, when required change rate K values are more than D, then it is 1 to export result, and welding sample flawless generates, corresponding product
For qualification；When required change rate K values are less than or equal to D, then it is 0 to export result, and welding sample has edge crack generation, corresponding production
